There are many types of coal chemical equipment, mainly divided into dynamic and static categories. such as the hydrogenation reactor, gasifier, reducing furnace, heat exchanger, lofty containers, pressure vessels and pipelines, valves belongs to static equipment,pump, fan, compressor, air separation equipment belong to dynamic equipment. The gasifier is the most important equipment of coal chemical industry. Most of the coal chemical projects needs to be converted into syngas. The air separation equipment is one of the key equipment of coal chemical industry, and the coal gasification and coal liquefaction are required to use a large amount of high purity oxygen, which have high technical barriers.
